The message was spotted last Thursday, I sent the dealership a message via SEAT APP, then I found I could do the battery swap myself. I have followed the manual to replace the batteries (having wathed a dealership change the battery) - checking the removed Panasonic battery it recorded 2.97v on the regular key and 2.99v on the spare key, hardly low voltage unless the overall voltage is 3.2v?.

New Batteries are Duracell CR2032 Exp 08/36. Batteries from key fob are original and the car was manufactured in October 2024.

Checked the new batteries work, started engine, a user settings update came up and approved that. Checked perimeter opening works, tried both keys everything looks fine.

Checked App, updated vehicle data and it still shows I need to replace the batteries! Now I know the APP is a pain in the Ar** at times, but I cannot figure out why it still saying the batteries "still" need replacing in the Key fob!

In the past when warnings appear - like the automatic speed indicator is disabled (usually come on in a hospital car park!) the error message goes off dashboard but remains on the App for a day or longer before clearing, but that stopped a couple of update back.

Likewise when I left an adult in the car accidentally locking them in, I could hear the car alarm, but the messages bell (top left) on the app remained white, it wasn't till I checked the App later I wondered why I hadn't had an email or the App buzz.. I clicked on the white notification to see the message and couldn't clear message until after the last App update!

Still waiting for the dealership to come back to me with a ludicrous quote for a battery change.

If anyone can advise - I'll buy them a virtual coffee!
